DURHAM, N.C. -- April 17, 2013

Cree, Inc. (Nasdaq: CREE) and Delta Energy Systems announce a breakthrough in
the photovoltaic (PV) inverter industry with the release of Delta’s new
generation of solar inverters, which utilize SiC power MOSFETs from Cree. The
use of SiC MOSFETs in the next-generation PV inverters can enable significant
new milestones in power density, efficiency and weight.

“The next-generation PV inverters from Delta are designed to set a new
milestone of power density by utilizing SiC MOSFETs,” commented Mr. Klaus
Gremmelspacher, head of research and development for PV inverters at Delta
Energy Systems. “The SiC MOSFETs from Cree were essential for us to realize
our goals for new, high-power inverters that are lightweight and have
industry-leading efficiency.”

Cree released the first silicon carbide MOSFETs, used for their ability to cut
losses and allow PV inverters to run at higher efficiencies and higher power
densities, in 2011 and a dramatically improved, second-generation SiC MOSFET
in 2013. Now, as a milestone product announcement, Delta Energy Systems, a
subsidiary of Delta Electronics Group, one of the world’s largest and most
respected providers of power management solutions, has incorporated Cree^® SiC
MOSFETs into its next-generation solar power inverter. Utilizing 1200V SiC
MOSFET’s from Cree in an 11kW PV inverter, Delta has already been able to
extend the DC input voltage range while maintaining and even increasing the
maximum efficiency of its previous products. The Delta 11kW booster, which
employs Cree’s SiC MOSFET and now has 1kV DC input instead of 900V, is
targeted for release in Q2 2013.

Dr. Scott Allen, senior director of marketing, Cree Power, remarked, “We are
pleased and honored to have Delta Energy Systems as a customer for our SiC
MOSFET. They are utilizing the 1200V, 160m-Ohm MOSFET, which has matured
rapidly since its release in 2011 and offers industry-leading performance and
cost. Advanced technology customers like Delta are now moving aggressively
forward with our SiC MOSFET technology, which enables reduced size, weight and
cost for PV inverters, from 20 to 50% when compared with silicon, while at the
same time maintaining or increasing efficiency.”

Packaged SiC MOSFETs from Cree are available from DigiKey and Mouser, and die
are available from SemiDice. For more information, please visit or contact a local Cree sales person or distributor.
